It has to do with the fasted state spiking HGH, adrenaline and other hormones. IF has been the only thing that has helped me lose weight over the long term as well as the only way of eating that has left me feeling healthier and given me energy. I am curious as to what harm you think I may be doing...
Just a phrase. Maybe "less effective" would have been more accurate. Thing is, running fasted will cause you to recruit your fat store for energy. But, when you run on low burn fuel that limits the intensity at which your run.
In other words, you can run longer -- and even more important -- a lot harder when you're carb fueled than when you are not.
That means, when you push your body into a higher active state, it will result in a much longer-lasting (many hours) fat burning capacity overall.
